Setting the Optic Output Power
The output power of the PPC is parametrized using the parameters "fibre-
optics cable (LWL) length" (C-0-0007). If plastic fibre-optics cables are
used, then the length of the fibre-optics cable connected to the
transmission output is set here. With glass fibre-optics cables, a length of
50.0 m must be set here.
Output power is set via switches S5A and S5B on the DSS 2.1 card (see
Fig. 8-16).
Output power is set via switches S20,2 and S20,3 on the front panel (see
Fig. 8-17).
If plastic fibre-optics cables are used then see Fig. 8-18. If glass fibre-
optics cables are used then see Fig. 8-19.

Checking the Fibre-Optics Cables
If both transmission rates and output power have been correctly set, (see
section "Clearing Errors", chapter 8.4) and communications still will not
function, then it is possible that the fibre-optics cable has a defect. In this
case, the distortion display will also light up.
The cause of a defective fibre-optics cable can be damage or poor
manufacture (e.g., connector mounting).
A defective fibre-optics cable can possibly be recognized by the fact that
at the end of the fibre-optics cable hardly any light is visible or the optical
fibre has been "pulled in backwards" into the connector. Check the face of
the connector. Other fibre-optics cable checks cannot be conducted
without the appropriate tools.
The only remedial action is the exchange of the defective fibre-optics
cable.
